The author discusses two sets of tracks excavated by paleontologists, which suggest that a smaller predatory dinosaur was following a larger grazing dinosaur and matching its stride. To explain this phenomenon, the author appeals to an analogy with modern predatory mammals, which match the stride of their prey immediately before striking. The author thus concludes that the predatory dinosaur was chasing the grazing one and attacked it immediately afterwards.
